There are rumors that Diamine makes all of Akkerman’s inks, and debate within those rumors as to whether they are simply re-branded or slightly altered version of Diamine inks. Either way, this ink is very nice.

This is an ink with one crazy long name, but luckily it’s good enough to justify it. There’s some serious discussion about whether or not Akkerman inks are simply re-bottled Diamine inks. I haven’t seen anything to convince be either way, but I will say that this ink is VERY similar to its supposed analog, Diamine Prussian Blue (which, coincidentally, I also love).
